In vivo harmonic generation microscopy (HGM) has been applied successfully in healthy human skin and can achieve a submicron resolution, similar to histopathologic examination, even at a penetration depth up to 270 μm. This study aims to investigate the clinical applicability of HGM imaging for differential diagnosis of nonmelanoma pigmented skin lesions. A total of 42 pigmented skin tumors, in...
Background and Aim: Basal cell carcinoma (BCC) is considered to be the most common malignancy in humans and occurs primarily in the skin especially in the head and neck region. Considering the high recurrence rate of the tumor, finding a marker for prediction of recurrence is very important. Cancer stem cells are a small subpopulation in the tumors that are related to tumorigenesis and recurren...
BACKGROUND Basal cell carcinoma (BCC) is the most frequently encountered neoplasm worldwide. While nodular BCC is the most frequent clinical subtype, other forms of BCC, such as superficial, cystic, morpheiform, infiltrative, and pigmented may also be encountered. CASE PRESENTATION We present the case of a 67-year-old male with a relatively well-defined infiltrative, pigmented plaque with mul...
Pigmented tumors have similar clinical features that overlap and hamper diagnosis. Dermoscopy increases the diagnostic accuracy of doubtful melanocytic lesions and has been used as a noninvasive tool in the detection of pigmented lesions (PLs) like melanoma, basal cell carcinoma, and pigmented Bowen's disease (pBD). Our objective was to show the dermoscopic features of 2 cases of pBD and compar...
Basal cell carcinoma superimposed on an old scar of localized cutaneous Leishmaniasis: A case report
Basal cell carcinoma (BCC) is the most common malignant tumor of the skin, which originates from the basal cell layer of the skin. It is more common in white race with skin types I and II. Some predisposing factors are sunlight, ionizing radiation, arsenic salts, PUVA and scar. We present a case of BCC, which appeared over an old scar of localized cutaneous leishmaniasis in a 49-year-old woman.
The incidence of skin cancer is increasing by epidemic proportions. Basal cell cancer remains the most common skin neoplasm, and simple excision is generally curative. Squamous cell cancers may be preceded by actinic keratoses-premalignant lesions that are treated with cryotherapy, excision, curettage or topical 5-fluorouracil. While squamous cell carcinoma is usually easily cured with local ex...
Background: The diagnosis of basal cell carcinoma is histopathological, but there are dermatoscopic criteria that confer high sensitivity and specificity to help the clinician improve its identification. However, blue-white variant does not totally meet these criteria, thus can be confused with other pigmented tumors. In literature reviewed, we found only five cases this variant. Aims: present ...
